Bornean Frogmouth

Batrachostomus mixtus

Small stout frogmouth with a face full of wispy whiskers. Males are dark brown overall; females are bright rufous. Restricted to Borneo’s central and southern mountain ranges, where it inhabits foothill and lower montane forest. Similarly-sized Sunda Frogmouth mostly found in lowland forest. Blyth’s Frogmouth is proportionally longer-tailed, with stronger white markings on the wings and underparts. Vocalizations vary and are poorly understood; frequently gives a mournful descending whistle and a fluid, rippling, downslurred trill.

Imperial Cormorant

Imperial Cormorant

Leucocarbo atriceps

Very striking cormorant readily identified by white neck. Locally common black-and-white cormorant of colder coastal waters. Often seen perched on inshore rocks and jetties, sometimes with Magellanic Cormorant. Nests colonially on low islands (rarely in lakes inland from coast) and jetties. Plumage varies regionally, with some birds black-faced and others white-faced; the two types breed together locally in the Strait of Magellan. Immature resembles adult but plumage duller overall, brownish above.

Hill Partridge

Hill Partridge

Arborophila torqueola

A brightly-colored game bird with an intricate head pattern and a body shaped like a football. Brick-red on the crown serves to distinguish the male from the similar Rufous-throated Partridge, while male Hill Partridge also lacks orange on the throat. Female lacks the male's white chest band and brick-red crown and has less orange on the throat than Rufous-throated. Moves around in convoys through dense vegetation in mid- to high-altitude forests.

Martens's Warbler

Martens's Warbler

Phylloscopus omeiensis

A bright and attractive small warbler with many virtually identical relatives. Breeds in foothill and montane forests, where it favors areas with a dense understory. Descends into lower elevations in the winter, when it often moves around with mixed flocks. Bright green above and yellow below, with a gray-and-black-striped crown and a bright yellow eyering; note intermediately strong crown patterning and distinct yellow eyering, often weak but not broken above the eye. Song is a series of lively whistles and chirps uttered in discrete bursts.
